Gastroenterology is the subspeciality during which internists diagnose and treat digestive system disorders. Some of the common problems gastroenterologists address are:

  • irritable bowel syndrome,
  • crohn’s disease,
  • inflammatory bowel disease, and
  • gastrointestinal cancers.

To diagnose these diseases, gastroenterologists utilize procedures such as endoscopy, colonoscopy, and liver biopsies.

With a median wage of $239,200 per year, gastroenterology is one of the most well-compensated areas within medicine. One of the main reasons why gastroenterologists enjoy such high earnings is the growing demand for gastrointestinal care, either from an aging population or an increased prevalence of digestive disorders in recent years. To provide specialized care, these internists can pursue further specializations, such as the one in hepatology, focusing on liver diseases or advanced endoscopic procedures. 

Recently, the field has developed, including advancements in endoscopic techniques. Notably, procedures such as endoscopic ultrasound and capsule endoscopy enhance diagnostic accuracy and minimize invasiveness. 

Same as other doctor’s specialties, a career in gastroenterology is physically demanding and requires continuous education. Nonetheless, the opportunity to make a significant impact on patients’ lives and the intellectual stimulation of diagnosing and managing complex gastrointestinal disorders make gastroenterology an attractive career choice for many physicians.

3. Oncology

Oncology is the subspecialty of internal medicine that dedicates its science to treating one of the biggest killers worldwide: cancer. To combat malignancies affecting different organ systems, oncologists employ various modalities such as chemotherapy, radiation therapy, immunotherapy, and targeted therapy. 

According to ZipRecruiter, oncology ranks among the highest-paid medical specialties, with a median wage equal to or greater than $392,661 annually. This substantial earning potential is influenced by factors such as the increasing prevalence of cancer and advancements in treatment modalities. To attract even higher salaries (as well as provide more detailed care), oncologists often choose to subspecialize within the field by becoming medical oncologists, radiation oncologists, or surgical oncologists. 

In the fight to beat cancer, doctors and researchers alike are working on developing new drugs and treatment plants. One of the most prevailing trends within this field is personalized medicine, where treatments are tailored to individual patients based on genetic markers and tumor characteristics.

However, becoming an oncologist comes with its challenges. Beyond the physical exhaustion that doctors face, oncology is emotionally demanding due to the health state of their patients (which can often be terminal). 

4. Pulmonology and critical care medicine

Pulmonology and critical care medicine are vital in internal medicine as they focus on diagnosing and treating respiratory diseases and critical illnesses affecting the lungs and airways. Pulmonologists manage conditions such as:

  • Asthma,
  • chronic obstructive pulmonary disease (COPD),
  • pneumonia, and
  • lung cancer.

To treat such diseases, they employ techniques like pulmonary function testing, bronchoscopy, and thoracentesis. In the position of critical care, internists manage patients in intensive care units (ICUs) suffering from life-threatening conditions such as sepsis, respiratory failure, and shock. To understand their role, think of the times when coronavirus was wreaking havoc in the world. The doctors treating respiratory diseases and treating patients in ICUs were in high demand.  

While COVID-19 is past us, the prevalence of respiratory diseases hasn’t decreased. And, this is one of the main reasons why these types of internists enjoy an average annual salary of $341,187. Internists within this specialty can pursue further education to specialize in sleep medicine, interventional pulmonology, or palliative care for terminally ill patients. 

Some recent developments that contribute to better care from these specialists include advancements in mechanical ventilation techniques, noninvasive ventilation strategies, and the integration of telemedicine in critical care settings, which could potentially impact future earning potential. 

Challenges associated with pursuing a career in this subspecialty include the demanding nature of critical care work, long and irregular hours, and the emotional toll of caring for seriously ill patients and their families. Nonetheless, the opportunity to save lives and provide essential care in critical situations makes pulmonology and critical care medicine a fulfilling and rewarding career choice.

5. Rheumatology

Rheumatology is the subspecialty of internal medicine that focuses on diagnosing and treating autoimmune and musculoskeletal disorders. These doctors manage conditions such as rheumatoid arthritis, lupus, osteoarthritis, and gout. To alleviate symptoms and improve patients’ quality of life, they employ a combination of medications, physical therapy, and lifestyle changes.
